Which card is used to connect directly to analog phones?

The FXS Voice Interface Card (VIC) is the correct answer because it is specifically designed to connect directly to analog phones. FXS ports provide the necessary ringing voltage and interface for traditional analog devices, such as telephones and fax machines. This card supplies the dial tone and is responsible for providing power to the connected analog devices, allowing them to operate seamlessly with the digital voice network infrastructure.

In contrast, the FXO VIC connects to standard telephone lines and is intended for integrating external analog phone lines into a voice network. While the VIC itself signifies a generic Voice Interface Card, it does not specify a particular connection type. Similarly, AIM, or Advanced Integration Module, refers to a broader category of modules used for various purposes, including voice processing, but it does not specifically address the connection to analog phones. Therefore, the FXS VIC is clearly the appropriate choice when it comes to interfacing directly with analog telephony equipment.
